AirGuard iMesh

Secure IEEE 802.15.4 Industrial Mesh Network

Concerns about the security of low-power wireless sensor networks have limited their use — until now.  AirGuard® iMesh enables wireless process automation that leverages enhanced security that has been independently validated by NIST (National Institute of Standards and Technology) offering a robust solution for wireless networks in industrial environments to combat cyber threats and malicious attacks. 

Made for Military – Used for Secure Industrial Operations
Designed for low-power and flexible integration, the iMesh Gateway and the iMesh Sensor Node together form a cyber-secure bridge linking sensors with IEEE 802.15.4, IEEE 802.11 Wi-Fi and Ethernet networks.  iMesh networks offer an affordable, robust ISA100-based solution for improving plant availability and efficiency by extending process monitoring functionality to plant-wide assets in oil refineries, utility factories, electrical power substations and metal and mineral processing facilities.   


  • Process Monitoring: Access previously unreachable input/output points and provide improved insight into plant-wide operations
  • Equipment Monitoring: Monitor equipment for a range of variables; vibration, corrosion, oil pressure, airflow, and extremely high temperatures
  • Plant Commissioning/Health and Safety: Temperature and pressure detection at multiple, space restricted points. Devices can be re-purposed after initial installation for cost savings
  • Energy/Conservation: Plant steam distribution systems can utilize the automated detection features to measure flow and the pH of stack emissions and identify leak and relief valve failures
  • Maintenance: Analyze, perform diagnostics, configure and calibrate device operation, installation and overall network performance
